4 Draw a ring around the number that is rational.

If \( f(x)=4 x-4, g(x)=-5 x^{2}+6 x-4 \), and \( h(x)=-5 x^{2}-5 \), find \( h(-2) \)

Find the slope and \( y \)-intercept of the line. \( f(x)=-6 x-5 \)

Divide using long division, \[ \frac{18 x^{3}+12 x^{2}-28 x+8}{6 x-4} \]

Find the slope of the line that goes through the given points. \( (9,-3) \) and \( (9,-4) \)

A car accelerates at a rate of \( 8.8 \mathrm{~m} / \mathrm{s}^{2} \) with a force from the tires of 19,976 What is the mass of the car?
